What are all the item changes you can see in second and following playthroughs in DS2? And which of them are present in the old "Dark Souls 2" game and which are at "Dark Souls 2 Scolar of the First Sin"?
Wiki lists a lot of changes, but also it says "Many merchants will add new items to their inventories" without specifying the merchants and items.
Another thing: the mentioned wikidot page seems to confuse DS2 and DS2sotfs, for example it says that the "Gower's Ring of Protection" is a new loot at ng+, but the page of Gower's Ring of Protection ring itself says that this is the case only for DS2, not DS2sotfs.
Also, is it correct, that at DS2sotfs you can get new loot only from bosses and there is no point to repeat thorough exploration of the areas?
